S1 1L, F, 6; B. W" HEGINBO STARTING DEVICE FOR EKPLOSIVE ENG-INES.,

APPLICATION FILED JULY 26, 1912.

Patented Aug. g5, WML

WT/VE the clutch member 8 is disengaged from the clutch member 9. Itwill thus be seen that although the shaft 11, shaft 10 and clutch member9 continue to revolve with the engine the rest of the starting apparatusremains stationary. Considering now the case when the engine has stoppedat or near the completion of its expansion stroke of one of the pistons,air is admitted but the. engine moves forward only until thedistributing valve closes and the engine does not start. In this casethe lever 16 is moved a to the left to its extreme position, thuscausing clutch member 8 to move up and out of engagement with the clutchmember 9 and causes the beveled tooth No. 23 to be forced against thepin 24, thus causing the clutch member 8 to revolve thereby rotating theshaft 6, and also the distributing'valv 1, which thereby opens thedistributing valve and admits air to a cylinder whose piston is on itcompression stroke. This causes the engine to move backward to thebeginning of the compression stroke, which is also the beginning of theexpansion stroke of a different'cylinder, and aswill be seen is anadvantageous position for starting when using compressed air.

By providing the lever 16 with .a rack 22 the clutch member 8 may beheld in any one of the three positions of engagement. lVe do not wish tolimit ourselves, however, to that class of starters which use compressedair, for our device is equally operated with, and may be applied to,those which introduce gas under pressure to a cylinderand then e lodethe gas, our device in this case being substantially the sameconstruction as described.

Having thus described our device what 7 we claim as our invention anddmire to secure by Letters Patent is:

1. In a starting device for internal combustion engines the combinationof a distributin valve, means for manually rotating sai distributingvalve, means for mechanically rotating the same, and means forconnecting and disconnecting the distributing valve with both of saidrotating means.

2. In a starting device for, internal combustion engines the combinationof a compressed air supply, a distributing valve adapted to distributecompressed air to the cylinders, means for mechanically rotating saiddistributing valve, means for manually rotating said distributing valveand means for connecting and disconnecting the distributing valve withboth of said rotating means.

3. In a starting device for internal combustion engines th combinationof a compressed air' supply, a distributing valve adapted to distributecompressed air to the cylinders, means for mechanically rotating saiddistributing valve, means for manually rotating said distributing valve,and means for connecting and disconnecting. the distributing valve withsaid rotating means; and a valve for controlling the supply ofcompressed air to the distributing valve,

said controlling valv operated by the said connecting and disconnectingmeans.

4. In a starting device for internal combustion engines the combinationof a compressed air supply, a distributing valve adapted to distributecompressed air to the cylinders, means for mechanically rotating saiddistributing valve, means for manually rotating .said distributingvalve, and means for connecting and disconnecting the distributing valvewith said rotating means, and a valve for controlling the supply ofcompressed air to the distributing valve and connected to said manuallyrotating means.

In a compressed air starting device for internal combustion engines, thecombination of a compressed air supply, a distributing valve adapted todistribute compressed air to the cylinders, a driving shaft'for r01tating said distributing valve, means whereby said distributing valvemay be rotated for a portion of a turn in a reverse directionindependently of said driving shaft and means for connecting anddisconnecting the distributing valve with said driving shaft.

6. In a compressed air starting device for internal combustion engines,the combination of a distributing Valve, a shaft for rotating saidvalve, a clutch composed of upper and lower'members, saidupper clutchmember provided upon its upper surface with a beveled tooth, a series ofpins. arranged concentricallyaround said shaft and mountedstationaryupon .a bracket. said pins adapted to act in conjunction with said beveltooth, said lower clutch member mounted upon a shaft and rotatedtherewith, means for raising and lowering said upper clutch member tothereby connect and disconnect it with said lower clutch member andfurther, to force it against said pins. 7
